The Back 9 Endurance Run is a unique 12/24-hour race set on a scenic 3.68-mile loop at the historic Keweenaw Mountain Lodge in Copper Harbor, MI. Participants will navigate through a blend of wooded trails, including the Back 9 Trails, and pathways across the Lodge’s historic golf course, enjoying stunning views of Brockway Mountain and Lake Superior along the way. Compete solo or in teams of 2 to 4, with each participant running one at a time. Runners are encouraged to bring headlights, as the event is held within the Keweenaw Dark Sky Park, known for its exceptional night sky visibility. The challenge lies in completing as many loops as possible within the designated hours.
